Patent attributes
An adjustable support for a panel is provided to allow control of the height and the tilt angle of the panel. The support includes a hollow cylindrical base having an outer diameter D1; a first hollow piston having an outer diameter D2 threadably engaged with the base; a second hollow piston having an outer diameter D3 threadably engaged with the first piston; a third piston having an outer diameter D4 threadably engaged with the second piston, such that D1>D2>D3>D4. A ball pod extends from the third piston and accommodates a ball attached to the panel. One or more stepper motors are provided, where each stepper motor is coupled to a bottom portion of a respective piston, and a rotor of each stepper motor is configured to rotate the corresponding piston, thereby causing the piston to move along a longitudinal axis of the support.
